Ecomatic Self-diagnosis
Performing self-diagnosis
Fault table

Notes:

  • ◆ In the following table all possible faults which can be recognised by the Digi Swing control unit -J327- and displayed on V.A.G 1551 with printer switched on, when interrogating contents of fault memory, are listed according to fault code.
  • ◆ If faults occur only occasionally or if the fault memory was not erased after rectifying the faults, these faults after a certain time are displayed as "sporadic faults".
  • ◆ If faulty components are found, test the wiring to the components additionally for short-circuits and open circuits according to the current flow diagram.
  • ◆ For the fault type "open circuit" first check connectors for contact corrosion or ingress of water, renew if necessary.
  • ◆ The fault code is printed out in the "rapid data transfer" mode only when the printer of V.A.G 1551 is switched on.
    Example: Fault code (5-position) 65535
  • ◆ For some faults only the fault code is shown on the print-out and the V.A.G 1551 display. Components checked are listed in the table.

Output on printer
V.A.G 1551

Possible cause of fault

Rectifying fault

No fault recognised!

If after successful repairs "No fault recognised!" appears, the self-diagnosis is concluded.
If the clutch electronics do not function fault-free despite self-diagnosis, repairs must be carried out.
